' WALL RADIATOR '1 Filed Aug. 7. 1929 2 Sheets-Sheet 2 Patented May 3, 1932 UNITED} STATES PATENT OFFICE ARTHUR B. MODINE, OF RACINE,,WISCONSIN, ASSIGNOR TO MODINE MANUFACTURING COMPANY, OF RACINE, WISCONSIN, A CORPORATION OF WISCONSIN WALL RADIATOR chamber being respectively provided withan air inlet and outlet, the air inlet being arranged relatively to the radiator chamber so that air introduced to the stack is compelled to pass through the radiator to be heated prior to its introduction to the air duct.

One of the principal objects of the inven-.

tion is the provision of a construction having a part capable of being arranged in a recess provided in the wall of a building and having a part which may extend beyond the wall and protrude into the room so that the room space for the device ,is minimized and a space is provided suflicient to receive a heating element of a required size to adequately heat the room which is to be served.

A further object of the invention is the provision of means whereby the radiator may be adjusted to incline it to thus insure flow of the heating medium from the inlet to the outlet of the radiator and further to providethe device with a humidifier.-

Another object of the invention is to provide a stack having the above enumerated and other objects and to combine a heating element therewith, to provide the structure with means whereby access to. the interior of the stack is facilitated and also to provide the device with means whereby the humidifier may be charged when this is found necessary or desirable.

Still another object of the invention is to provide a stack in which the radiator is connected therewith as a unit or is separable therefrom.

The invention will be explained and more readily understood when read in conjunction with the accompanying drawings which illustrate various modifications which may beisofted to, it being therefore obvious that other changes and modifications may be employed without departing from the-spirit of the appended claims forming a part hereof.

Referring now moreparticularly to Figs. 1 to 3 of the drawings, the numeral 10 generally. designates a combination heat exchange device and cabinet. housing for the same. A recess 14 is provided in a wall 11 of the building structure to receive the rear projecting portion of the device and provide a maximum radiator space with a minimum of encroachment upon the room space.

The front portion of thecabinet comprises a plate 17 suitably fastened to a pair of corner angle posts 21 fastened to the end walls 16. The rear wall of the cabinetcomprises a wall 15 having its upper portion vertical for positioning adjacent a wall of the room and its lower portion extending rearwardly beyond said wall 15 to provide space for a horizontally extending radiator unit. The wall 15 projects downwardly into contact with the floor and together with the posts 21 supports the radiator unit and cabinet. By reason of the increased dimension of the cabinet, due to projecting the wall 15 rearwardly, additional space is provided for the h01i+. zontally extendin radiator unit without encroaching upon the room space.

An apertured cover 18 closes the-upper end of the cabinet and a curved plate 19'positioned below and adjacent the cover 18 servesto deflect the heated air coming from the radiator unit outwardly into the room. By

forming a fluid tight joint between the late 19 and the walls 15 and 16, a humidi ying tank 22 may be provided, moisture being permitted to escape through said aperatures. A grille plate 2.0 is positioned in the front wall of the cabinet immediately underneath the curved plate 19. j

The radiator unit comprises a plurality of horizontally extending tubes 24 connecting oppositely positioned header tanks 23. The radiator unit -is positioned in the lower end of the cabinet and is in spaced relation to the fioor. The front plate 17 terminates in substantial alignment with the bottom of the heating unit, leaving an air inlet between the lower edge of the plate and the floor. A plurality of fins 25 serve to accelerate the transfer of heat from the unit to the air passing between the tubes and upwardly and outwardly through the grille 20.

Heating fluid is admitted to the radiator unit through a feed pipe 26. The feed pipe 26 projects upwardly through the floor and is-connected with a nipple 32 by means of a union 31. The fluid coming from the pipe 26 empties into one of the tanks 23. The tubes 24 provide for the flow of the fluid to the other of the tanks 23 from which it passes through a tube 26 connected by means of a union 31 and a nipple 32 similarly to the connection described for feed pipe 26.

The flow of air through the device is controlled by a damper plate 27 fixedly mounted on arotatable rod 28. The damper is manipulated by means of a knob 29 projecting tirhroulg'h one wall of the device, as shown in The structure shown in Figs. 4 to 6 substantially corresponds to that shown and previously described, however, it difiers in that the heating element 33 is arranged for vertical adjustment with respect to the stack generally designated 34, this adjustment being provided for to allow the radiator to be tilted or inclined to insure flow of the heating medium from the inlet to the outlet. The means for accomplishing this last mentioned feature includes slots 35 and 36, respectively, provided in the opposite end walls 3737, and a screw-threaded stud 38 which projects from the radiator 33 through the slot. The stud has a nut 39 whereby the radiator may be held in any one of its adjusted positions with respect to the radiator stack generally designated 34. The radiator stacks respectively generally designated 10 and 34 are each formed of a sheet of metal bent to provide the side walls 3737 and the rear wall such as 40. This rear wall such as 40 and the wall 15 is bent inwardly toward the radiator chamber to divide the space above the chamber to produce a recess 41 and the duct 45, the recess being provided to receive a cross piece such as 42, studding 43 and wall 44. The upper termination of the duct 45 is curved outwardly as indicated at 46. An

ator and become heated before it is permitted to escape through the opening 47. The structure shown in Fig. 4 contemplates the use of a removable cover plate 49 which provides a closure for the opening between the end walls 3737, the closure being removable to permit access to the interior of the stack to facilitate cleansing thereof or to make necessary adjustments" of the radiator 33 should this become necessary. The closure49 is held relatively to the remaining structure by any suitable means, that herein shown includes screws 50 which are passed through the angle iron legs 51 into threaded engagement with brackets 52 secured to the side walls such as 37 of the stack.

The structure shown in Figs. 4 to 6 is enclosed within a casing 53 including-a cover 54 which caps the upper end of the device and assists to give this portion of the structure a finished appearance. The side walls 3737 of the structure shown in Figs. 4 to 6 have a portion thereof removed near the. forward end thereof to provide openings 55 and 56 to thereby allow greater freedom of the passage of air from the room and through the radiator. .-From the foregoing description of the structure, it is manifest that a relatively large radiator chamber is provided and in which that portion of the stack above the radiator chamber is formed to provide a recess for the reception of a wall of the building structure and in addition is constructed to form an air duct, the combined structure cooperating to provide for the accommodation of -a re atively large radiator and means for introducing heated air to the room in which the room space utilized by the device is reduced to a minimum.
